README

TYPO3 CMS Composer installers

This package acts as composer plugin in order to download and install TYPO3 core and extensions and put them into a directory structure which is suitable for TYPO3 to work correctly.

The behavior of the installer can be influenced by configuration in the extra section of the root composer.json.

Options for extension composer.json

extension-key (required)

    "extra": {
        "typo3/cms": {
            "extension-key": "bootstrap_package"
        }
    }

Specifies the extension key. This is mandatory and extensions will stop to work with version 4 of this package if not provided properly.

A warning is show by Composer if this key is missing in a extension.

Options for project composer.json

web-dir

    "extra": {
        "typo3/cms": {
            "web-dir": "public"
        }
    }

You can specify a relative path from the base directory, where the public document root should be located.

The default value is "public", which means a "public" directory at the same level as your root composer.json.
